Create a new string by alternately combining the characters of two halves of the string in reverse in C++ Program
In this tutorial, we are going to write a program that creates a new string by alternately combining the characters of the two halves of the string in reverse order.
Let's see the steps to solve the problem.
Initialize the string.
Find the length of the string.
Store the first half and second half string indexes.
Iterate from the ending of the two halves of the string.
Add each character to the new string.
Print the new string.
Example
Let's see the code.
#include <bits/stdc++.h>
using namespace std;
void getANewString(string str) {
int str_length = str.length();
int first_half_index = str_length / 2, second_half_index = str_length;
string new_string = "";
while (first_half_index > 0 && second_half_index > str_length / 2) {
new_string += str[first_half_index - 1];
first_half_index--;
new_string += str[second_half_index - 1];
second_half_index--;
}
if (second_half_index > str_length / 2) {
new_string += str[second_half_index - 1];
second_half_index--;
}
cout << new_string << endl;
}
int main() {
string str = "tutorialspoints";
getANewString(str);
return 0;
}Output
If you execute the above program, then you will get the following result.
